POCKET-CASE.

SPECIFICATION forming part of Letters Patent No. 763,722, dated June 28, 1904.

Application filed April I8, 1903. Serial No. 153,306. (No model.)

.T0 all whom t may concern.'

Be it known that I, FRIEDRICH CHRISTIAN, a subject of the Kingof Prussia, German Emperor, residing at Bad Soden in Taunus, Germany, have invented certain new and useful Improvements in Pocket-Cases, of which the following is a specification.

The present invention relates to improvements in cases, boxes, and the like, more particularly to pocket-cases of that class produced of pasteboard.

It has for its object, among other things, to do away with the use of metal clamping-pieces as in the making of such cases as heretofore. Also in the latter the case-sections were closed on one side by superposing the edges of the same, also being closed at the bottom with the edges abutting and secured by means of a metal clamp. According to Ymy invention, on the contrary, both the side and bottom edges labut each other and are joined together by means of an interiorly-applied adhesive strip.

Said invention consists of the combination and arrangement of parts, substantially as hereinafter more fully disclosed, and specifically pointed out by the claim.

In the accompanying drawings,which show, by way of example, the preferred form of carrying this invention into effect, Figure l is a perspective view thereof. Fig. 2 is a vertical section, and Fig. 3 is a horizontal section of the same.

Throughout the several Views like parts are marked with like letters of reference.

In the carrying out of my inventionI produce, as usual, the pocket or oase in two sections a and b, respectively, adapted, as shown, to slide one within the other. The side seams at c and the bottom seams atei are closed by applying interiorly of lthe respective sections, along said seams, additional strips of like material. In order to effect the closing of the seams perfectly tight, said sections at those points are subjected to a peculiar pressing. Said seams are produced similarlyv to those of a leather case, the meeting edge portions/of the sections being outturned or raised, as shown in the drawings, t'o reinforce the joint,

so that in applying pressure thereto said outturned or abutting portions are pressed together. The pressing-mold used for the aforesaid purpose is made in such a way that after the pressing has been effected it is completely closed` and contains the ready-made case. As the material of the sections of the pocketcaseis heated during the pressing it expands, so that if the requisite amount of material be used the space left by the pressing-dies must be completely filled up, and a perfectly tight closing of the edges will be obtained. Prior to the pressing operation the strips are moistened with adhesive material. This method of manufacture enables the imprinting simultaneously with the pressing `operation of a design upon Ythe pasteboard case, which design not only appears upon the lateral surfaces of thecases, but also upon the surfaces between the corner edges and the seams. In order to make the seam resemble that of a leather case, elevations or depressions f, resembling stitches, may be produced at the edges of said seam. `Such cases may be made for use as cigar-cases, cigarette-cases, pocket medicine-cases, and the like. They are cheaper to make and of more elegant appearance than the cases hitherto made with metal clamps or clasps.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A cardboard pocket case or receptacle of the character described, composed of two parts, each formed of one piece of material having its edges extended beyond the general surface of the same thereby reinforcing the joint, said edges secured together by a strip, provided with adhesive material, along the seams interiorly of the case, the seams being covered and protected by said strip.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

FRIEDRICH CHRISTIAN.
